Physical Description

1 online resource (9 p.)


Data sharing among organizations has the potential to 1) decrease long-term costs of obtaining and maintaining data and 2) to facilitate data consistency and accuracy. Consistency includes both completeness and currency, while accuracy includes positional and relative accuracy of transportation features and their attributes, i.e. any data element related to roads or other transportation infrastructure.

ORBIT, the Oregon Road Base Information Team, is an ongoing effort to create an accessible and comprehensive GIS transportation base for use by public and private agencies with shared stewardship through stakeholder partnerships and standards. ORBIT is occurring concurrently with an effort at the national level to develop an NSDI Framework Transportation Identification Standard to enhance the development and implementation of principles and procedures for sharing of transportation data
